burned are piled. The firing of the chambers and the consequent burning of the bricks is done progressively. The difficulty encountered in thesekilns is, the moisture laden vapors are not carried from the chambers with suliicient rapidity to the stack, but the vapors are permitted to remainin the chambers for such length of time that they will condense on the brick and have a tendency to discolor the latter.

One of the main objects of my invention, therefore, is toprovide means for the rapid carrying of the vapors from the chambers to the stack. I accomplish this object by providing draftflues in thepartition walls between the chambers, and connecting these i'lues with the chambers respectively and the stack. I

Other objects of, andadvantages obtained by my invention are fully set forth in the following detailed description of my invention.

in the accompanying drawings: Figure 1 is a side elevation ofa portion of a brick kiln embodying my improvement; the draft openings for the different chambers are not shown; Fig. 2 is a plan view of the parts shown in Fig. 1; Fig. a longitudinal vertical section of the kiln taken approxi matelv on the line indicated by the arrow 3 in Fig. 2; Fig. i is a view similar to Fig.

3,'but taken on the line indicated by the.

arrow 4 in Fig. 2; Fig. 5 is a longitudinal horizontal section taken on the line 5 of Fig. 1; Fig. 6 is a transverse vertical section taken on the line 6 of Fig. 3, looking toward the left; Fig. 7 is a view similar to Fig. 6, but taken on the line 7 of Fig. 3; and Fig. Sis a horizontal section taken on the line 8 in Fig. l.

The kiln A comprises a series of arched burning chambers, a, separated by the parti'- tion walls 6, in each which walls is located a small opening 0. These openings provide direct communication between the burning chambers. The openings, 0, in adjacent partition walls areloeated on opposite sides of the kiln. See Fig. 7. Each burning chamher, a, is provided with doors, (Z, in its op-- posite end walls, which doors form an entrance way through which the brick may be ,carriedin and piled up in the chamber. The

top of the kiln is provided with a number of parallel fuel openings 6, e, which connect with the interior of the chambers, a, and form means for introducing the fuel into said chamber from the outside. The end walls of each chamber are provided with small openings 7", located in the same vertical planes as the fuel openings 6. After the brick is piled in the kiln chambers, a, the wickets which seal the doorways are made with small openings 9 (represented by broken lines in Figs. 1, 3 and a), such openings being located in the same vertical plane as the fuel openings 6.

Extending longitudinally beneath the floor of the kiln are the main draft flues h connecting directly with a smoke-stack, not shown. in some instances 1 have found it advisable to install suction fans in these main fines for the purpose of establishing an induced draft therethrough.

Each wall of the kiln, at the points of junction with the partition walls Z), is pro vie ed with vertical draft flues, i, the tops of which are enlarged as shown at y'. The vertical flues, z, are arranged alternately on opposite sides of the kiln, and also at the end of the partition walls farthest from the openings 0'. Each partition wall Z) is provided with a longitudinal horizontal flue 7c connecting with the enlarged portion j, of the vertical flue. Furthermore, each flue is is made witha, number of lateral draft openings, m, which connect with the fuel openings a (see Fig. i) and thereby with the interior of thekiln. The enlarged portion j of the vertical flue, z, is provided with a lateral flue m, which also connects with the interior of the fuel chamber through the side walls. A. damper n, operated from the top of the kiln by a handle n, controls the draft through the openings m and n. The fuel openings 6,6 are provided, with caps r, which may be removed when fuel is being placed in the chamber, and the openings j", g are also closed except when it is desired to rake down the fuel.

The advantages of my construction over 7 down and prevent it from being piled up under the fuel openings 6, 6. Lastly, by locating the draft openings, m, in the partition walls, I), the water-smoke developed by the burning of the green brick will be drawn directly out of the chamber instead of the end walls.

of being required to traverse the whole chamber, as is the case in present structures, where the draft openings are in the floor Under the latter condition, the water-smoke condenses and discolors the bricks, which I avoid'by taking the smoke directly out of the chamber before it has time to condense.

I claim:

j 1. Ina brick kiln of the character described comprising a series of adjacent chambers and partitions separating such chambers, the combination of draft fiues extending longitudinally in the partitions and having inlets from the related chamber,

a main smoke passageway extending lengthwise of'the kiln, branch passageways in the partitions, said branch passageways connecting the draft fiues with said main smoke passageway, dampers controlling those ends said branch-passageways connecting with said draft fines, and auxiliary'inlet passageways connecting the interior of the chambers withsaid branch passageways in l the partition.

2. ln brick kiln of the character described comprising a series of adjacent chambers and partitions separating such chambers, the combination of fuel'openin-gs extending through the roof of the kiln and located alongside the partitions, covers for such fuel openings, longitudinal draft flues in the partitions, the respective draft fiues Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

being in communication with the related of said fuel openings, a main smoke passageway extending lengthwise of the kiln, branch passageways in the partitions connecting the draft-fines with said main smoke passageway, and dampers controlling those ends of said branch passagewaysconnecting with said draft-fines.

3. In a brick kiln of the character described comprising a series of adjacent chambers and partitions separating such chambers, the combination of fuel openings extending through the roof of the kiln and located alongside the partitions, covers for such fuel openings, longitudinal draft-fines in the partitions, the respective draft flues being in communication with the relatedof said fuel openings, a main smoke passageway extending lengthwise of the kiln, branch passageways in the partitions connecting the draft-fines with said main smoke passageway, dampers controlling those ends I of said branch passageways connecting with said draft-fines, and auxiliary inlet passageways connecting the interiors of the'chamberswith said branch passageways in the partition. i

4:. In a continuous brick kiln comprising a plurality of arched chambers separated by in the ceilings of the chambers, fuel control openings in the end walls of each chamber,

and said fuel control openings being located.
